We are trying to start my brother's 66 Mustang with MS. We have MS-I on a V3 board with MSNS-E version 29q running fuel only with MegaTune 2.25. The engine is a roller 5.0 with TrickFlow heads and Stage 1 cam with 30lb Ford Motorsports fuel injectors. It trys to start but only runs for 1 second before dying. Then we have to flood clear it to get it to start again. I know we are running too rich, but I don't know what to change. What should our Pulse Width be set to for starting and then after start enrichment? I've attached a coulpe datalogs of what is happening. Please look and see what might be off and what we must do to correct it.
